She can be developed by giving her a backstory. Maybe she had a difficult childhood that made her so self - centered. This would make readers understand her actions better. For instance, if she was bullied as a child and now uses her popularity as a shield.
One idea could be Scarlet Lady actually learning to be a better hero over time. Maybe she starts to see the error of her ways and tries to make amends with Ladybug and Chat Noir. For example, she could start training harder to improve her skills instead of relying on her looks all the time.
In the fanfiction world, Lady Wifi could also have a sort of redemption arc where she realizes the error of her ways and in the process, falls in love with Chat Noir. Chat Noir, being the flirty hero he is, could initially be intrigued by her new - found good side and over time, real feelings develop between them.
Ladybug and Chat Noir are obviously very popular. They are the main characters in the original series, and in fanfiction, people love to explore their relationship further. Writers often create scenarios where they grow closer or face bigger challenges together.
In some fanfictions, there are storylines where new Miraculous holders from different parts of the world join the fight. These new characters bring in unique powers and cultures, adding more depth to the Miraculous universe. For example, a holder from an Asian country with a Miraculous related to an ancient mythical creature.
The story in this comic is quite complex. It involves characters dealing with deception and uncovering hidden truths. There's a lot of action and drama to keep you engaged.
